Question

Two identical cars are traveling at the same speed. One isheading due east and the other due north.Which statement is trueregarding the kinetic energies and momenta of the cars? A) They have the same kinetic energies and the samemomenta. B) They have the same kinetic energies, but differentmomenta. C) They have different kinetic energies, but the samemomenta. D) They have different kinetic energies and differentmomenta. Two identical cars are traveling at the same speed.
